Carbon nanotubes form extremely tight contacts with neuronal cell membranes, creating shortcuts between neurons for enhanced excitability. This breakthrough has the potential to treat traumatic brain injuries, Parkinson's disease, and severe depression by bypassing faulty brain wiring.
Researchers have identified genes controlling snail shell handedness, similar to those used by humans to set up left-right asymmetry. These findings suggest that the same genetic pathway has been responsible for establishing left-right symmetry in animals for 500-650 million years.
A newly identified gene MACC1 has been found to be a powerful predictor of colon cancer metastasis. Patients with low MACC1 levels have a longer life expectancy compared to those with high MACC1 levels.
Researchers have found that men outnumbered women in the ancient African exodus, tracing variations in X chromosomes and non-sex chromosomes to support their conclusion. The study's lead author notes that these findings align with anthropologists' teachings on hunter-gatherer populations.
Researchers have identified a single gene, G9a, controlling cell flexibility in embryos and potential for medical cell replacement therapy. This discovery sheds light on the process of cell differentiation and could pave the way for new approaches to reprogram cells in a controlled manner.
Researchers have discovered that two cardiovascular proteins, SRF and myocardin, work together in the brain's blood vessels to decrease blood flow and impair amyloid beta removal. Studies in human cells and mice show that these proteins increase toxic amyloid beta levels, contributing to Alzheimer's disease.
Scientists have successfully recreated the hallmarks of a genetic disorder in a lab dish using patient-derived induced pluripotent stem cells, which can now be used to study and develop new therapies for genetic diseases. The disease-specific cells retain the same traits as those affected in patients with spinal muscular atrophy, allow...
Nationwide Finnish study reveals that well-developed outpatient services and higher outpatient-to-inpatient ratios are associated with a significantly reduced risk of death by suicide. Emergency services operating 24/7 also showed a risk reduction of 16%.
